I remember reading somewhere an article that described a means by which a *binary* bitmap image could be manipulated by TeX as a character (glyph?) I think it must have been a TUGboat or TeXhax, but I can't find it. Any pointers? (I'm not referring to halftoning etc) Cheers, Ian Green img@eng.cam.ac.uk
